            <p>Feature digitizing is in freehand mode by default.  In freehand mode, the mouse is treated as a pen.
            Drawing begins on mouse down, continues with every mouse move, and ends with mouse up.</p>
            <p>To turn freehand mode off, hold down the shift key while digitizing.  With freehand mode off, one
            vertex is added with each click and double-clicks finish drawing.  Freehand mode can be toggled on and off
            at any time while drawing.</p>
